ferroli 77ff combi problem please help

Before I would spend £200 ish on a pcb I'd want to check corgigazza's list and anything else I could think of. AND work out from the manual exactly what the sequence should be.

(I think its an oldish boiler, so then I'd look for a secondhand board!)

The blue wire coming off the aps is the one that becomes live when the fan runs and the aps has functioned properly.
Brown wire common
Blue normally open
black normally closed.

After the aps its usually the pcb on these. Theres 3 relays on the right hand side of the pcb and its often the lowest of these [relay 3] that is blackened inside the plastic cover. In desperation I have occasionally got away temporarily with removing the cover and cleaning the terminals with an emery board

PCB is VMF6.1 part number 3980254/0
APS is part No. 3980014
